In 2008, Sun Hongjun took the lead in founding Shanghai Awin Electronic Technology Co., Ltd. Awin is a high-tech company that focuses on mixed signal, analog, RF and other IC design, focusing on mobile phones, wearables, smart hardware, IOT and other consumer electronics fields. Since the establishment of the company, Awin has adhered to the concept of "customer needs are the only reason for Awin's existence, and a high-quality team is Awin's greatest wealth", close to domestic mobile phone solution design companies, and quickly launched new products. Among similar domestic manufacturers, the customer coverage rate ranks first, and is striving to catch up with international brands. As Awin continues to develop brand customers, Awin successfully listed on the New Third Board (code NEEQ: 833221) in July 2015. Since its listing, it has been widely used by many domestic brand mobile phones. Since its establishment in 2008, Awin has applied for more than 50 patents, obtained 23 patent technology authorizations, and obtained more than 80 integrated circuit layout registration protections. Currently, more than 50 chips with independent intellectual property rights are hot-selling. As a fabless chip design company, we outsource all our production to well-known international and domestic manufacturers such as TSMC, CSMC, Unisem, ASEN, Changdian Technology and Changdian Advanced. In order to ensure first-class quality, we have implemented a strict quality control process for outsourced product production. In December 2009, the company passed the SGS certification of ISO9001:2008 quality management system.

AW8155FCR Overview

second generation music amplifier

Features

•AW8155 is a second-generation music amplifier with anti-breaking sound, super TDD suppression and ultra-low EMI. Ultra-low distortion and unique anti-breaking sound technology eliminate the breaking sound produced during playback, bringing you wonderful music enjoyment.


•AW8155 adopts Awin’s proprietary RNS technology and clean sound technology to effectively suppress the generation of TDD noise.


•AW8155 has two power levels of 0.65W and 0.85W, suitable for different speaker specifications, strictly controlling power output and effectively protecting the speakers.


•AW8155 has built-in excellent Pop-Click noise suppression circuit, which effectively avoids Pop-Click noise when the chip is turned on and off.


•AW8155 has built-in over-current protection, over-temperature protection and under-voltage protection functions, which effectively protect the chip from being damaged under abnormal working conditions.


•The AW8155 is available in a tiny 1.5mm x 1.5mm FC9 package and is rated for operation over the -40°C to 85°C temperature range.
